In the Italian translation there is a bug, probably due to a misunderstanding, probably generated by having done the translation without accurate knowledge of the context.
In the activity tab of the season pass, as in the following image, the term “tier” is translated into “Livello”, which actually means “level” and not “tier”.
So an Italian player could try to skin level 5 animals, and think that the card is buggy.
Furthermore, at a purely UX level, it is not clear what is meant by Tier 5 animals. It would be useful to insert the level in brackets, for example:
Skin Tier 5 animals (level xx to 60+)
Or similar label
(even me, after 1500 hours of play, struggle to understand which animals are tier 5, until I kill and skin them)
